From the article that we all read before commenting:

> Using its app, Fixed customers could snap a photo of their parking ticket using their phone’s camera, and then Fixed would check against a variety of common errors before writing a customized letter to the city on the user’s behalf.

The app is meant to do the ticket-checking, not the user. Additionally the website itself for Fixed mentions that they do the checking, not the end user.

I am questioning why he felt the need use the service when he knew that the parking tickets were legitimate.

Yup. a) it was my wife that used Fixed and I do remember rolling my eyes when she explained the ticket she submitted b) we're always fascinated by what seem to be too good to be true SF startups so we typically try them out, and c) they aggressively market it as a no-lose proposition and put their flyer on every car that gets ticketed in SF.

But yeah, you're entirely right.
